  1. Privacy-Conscious Individuals:

    • Ideal for users who prioritize privacy and do not want their communications to be accessible by third parties, including service providers and advertisers.

  2. Journalists and Activists:

    • The robust encryption and security features make Signal a popular choice among journalists, activists, and others who may be concerned about surveillance and censorship.

  3. Everyday Communication:
